Application filed February 5, 1914. Serial NO. 816,832.

T0, all about it may concern 7 Be itlmown thatI, J HN F. DAVEY, a citizen of theUnited States, residingat Beverly, in the county of EsseXand-State ofMassachusetts, have invented certain Improvements in Fastener-Setting Machines, of which the following description, in connection with the accompanying drawings, 18 a specification, like reference characters;

on the drawings indicating like parts inthe several figures. j TlllSJIlVQIltlOIl relates to machines for settingfasteners insheet material and is herein,

chines for setting eyelets I or other fasteners in parts of bootsandshoes.

One object f theinvention is to provide a machine of-such;construction that it may be operated either, mechanically or by foot power without substantial change in general organization. Such a machine. is" advantageous because it can be .used in a: larger field thana machine whichis adaptedto be operated only mechanicallyor'only by foot power.

In thiseonnection an important feature of the invention consists in the. provision of toggle mechanism for operating the movable; setting ,dieso disposed'that a treadle rod may be connected. adjacent to its knuckle, joint when it is desired to operate the machine by foot power, said mechanism being at thesametime adapted-to be connected to poweractuating means when it is desired to operate the machine by power.

Another. feature of the invention relates tothe provisionof a novel form of punchingmechanism whereby the work may be perforated, preliminarily to the insertion and clenching ofan eyelet. As herein shown the punchingmechanism is arranged tobe operated by foot; power from a treadle'and suitable, connections 7 are provided whereby the initial movementof the treadle is effective for actuating the punching device while its, further movement is effective for toithe organizationtofthe punching and setting ,mechanism of fastener.-settingma Specification of Letters Patent.

chine, and consists in providing a pair of setting devices and a pair of punching devices, together with power operated mechanism for effecting the action of one of said pairs and manually operated mechanism for eifecting the action of the other of said pairs.

It is believed that this combination has never before been employed in a fastener setting machine. 7 I

Still another feature of the invention relates to the'mechanism for moving the raceway to and from its; deliverin'g position.

It is desirable that the machine should come to rest with its raceway in its delivering position and that the raceway should be moved out xof range of the setting die as soon as the machineis set in:0peration and maintained in an inoperative position until after the setting operation so that there will be no danger of striking the setting die. This is effected, as herein shown, by providing-a sliding cam bar movableto displace and hold the raceway and adapted to be actuated either fronithe main shaft, when the machine is operated mechanically, or from some point in the mechanism for actuating the setting device when the machine is operated by foot power. i

to be Other features of the invention consist in an improved general organization whereby other jaws of different shapes may be sub- Parts of the raceway actuating mechanism are so associated with parts of the starting and stop-- ping mechanism that a common mounting" stituted as occasion may require.

may be utilized and the machine thus simplified in this respect.

These and otherfeatures of the invention will be best understood and appreciated from the following description of a pre-' ferred embodiment thereof selected for purposes of illustration and shown in the ac companying drawings, in which, E

-Fi-g.- 2 is a view in elevation, partly in section, of the H other side of the machine;

Fig. 3 is a fragmentary View of the raceway and connections; 7

Fig. 4- is a view in side elevation of portions of the starting and'stopping mechanism; I

Fig. 5 is a view in perspective of these and other portions of the starting and stopping mechanism; 7

Fig. 13 is a fragmentary view showing the punching die and lower setting'device in initial position;

Figs. 7, 8 and 9 are views in perspective showing the operating parts of the machine in different positions, and

Fig. 10 is a view in section showing the setting devices in clenching position.

The machine frame 2 has bolted to it a detachable lower jaw 1 having at its outer end a split socket for the lower setting device 6 which is adjustably maintained in position by a clamping bolt 8. The jaw i is made detachable so that it may be replaced by other jaws of different shapes in case it is desired to adapt the, machine for any particular class of work.., To insure properly locating the jaw the frame .is provided with a shouldered surface and the base of the jaw is shaped to fit the surface of the frame.

The upper port-ion of the frame is pro vided with vertical bearings for the reciprocatory plunger 10 which carries at its lower end the upper setting die 12. The die 12 is shaped at its end to fit the flange of the eyelets to be set and is provided with a yielding center spindle 14. The plunger 10 is reciprocated by connections with toggle li11ks20 and 22 the toggle links being so disposed as to occupy a substantially horizontal position as the uppersetting die 12 approaches its clenching position. The plunger 10 is connected at its upper end to a short link 18 which in turn is connected to the forward end of a bell crank lever 16 pivotally mounted on the shaft 17. The lower end of the bell crank lever 16 is connected to "the toggle link 20 which is U- shaped and has one branch extending on each side of the lever 16 and of the other toggle link The toggle links and the lever 16 are disposed within the machine frame and the link 2 has a projection perforated at 23 for connection with a treadle rod in case the machine is to be operated by foot power. The machine is herein shown as adapted tov be operated from the power driven shaft 30 and consequently the treadle rod by which the toggle might be straightened is omitted from the. drawings.

The toggle link 2 is secured to a rock shaft 21 which extends through the sides of the machine frame and is provided on one end with a crank arm 25 as shown in Fig. 2.

The arm 25 is connected through an oscillatory link 26 to crank pin 28 which projects from a disk fast on the driving shaft 30. hen the shaft 30 is turned from the position shown in Fig. 2 the link 26 is moved forwardly, the toggle straightened and the forward end of'the lever 16 depressed, thus lowering the setting die into clenching poltiOIi.

Eyelets are supplied to the setting die 12 by a raceway 68 mounted upon a journal pin extending between upstanding ears on the machine frame. The raceway carries a hopper 66 of the usual construction. The latter contains an agitator arranged to be actuated by a crank arm 64: through connections with the bell. crank lever 16. For this purpose a stud 62 is provided on one side of the lever 16 and is arranged to oscillate aninterposed bell crank lever 60 which is connected through a universal joint to the crank arm 64.

The raceway 68 is yieldingly maintained in its delivering position by a spring actu ated rod 69 pivotally connected at one end to a stud 67 on the raceway andextending through the machine frame to the opposite side where it is provided with a retaining nut. The raceway, after delivering an eyelet, is'swung outwardly against the compression of a spring which encircles the rod (39 and the latter, when'permitted, swings the raceway inwardly to a delivering position determined by an adjustable stop set in the machine frame as shown in Fig. 7.

For the purpose of moving the raceway out of'its delivering position there is provided, between the raceway and the machine frame, a cam bar 'i' lhaving a tapering end arranged to engage a roller 72 on the raceway. end and guided in its reciprocatory movement by a stud 63 set in a boss on the machine frame as shown in Fig. 7. The cam bar 7% is reciprocated in a path parallel to the length of the raceway by a cam lever 76 pivotally mounted 011 thetransverse shaft 36 and carrying at its rear end a cam roller which runs upon a cam 78 on the driving shaft 30. The shape of the cam 78 is shown in dotted lines in Fig. ei fromv which it will be seen that the lever 76 is oscillated to move the raceway outwardly early in the cycle of the machine and held outwardly until just before the machine is brought torest.

In order .to perforate the work preliminarily to inserting an eyelet there is provideda sectional punchingdie plate comprising the two sections 82. These are arranged to force the work upon the sharpened spindle of the lower setting die 6 to per-= forate the work and are then separated to permit the passage of an eyelet. The punchmg d e sections 82 are pivotally mounted uponthe carrying bar whlch in turn is moimted to swing vertically about a horizontal shaft Slas an axis. The punching The cam bar is slotted at its lower.

- die is, depressed through/the treadle rod 85 connected to the 'treadle 86"an'd is returned to its initial position by a compression springlwhich-encircles the upper, end f the treadle mama rests on the base of the frame as shown in Fig. a The upper: or initial position of the bar 80 determined by an adjustable @stop, 83, and its lower position is limitedlby an adjustablelstopfifil in the jaw 4 Secured ,tothe lower faceof the bar 80 is a thin plate 7 8 4 I perforated to fit overthe lowerfsetting dieg6 and arranged to act as a stripper for removing. the work with a clenched eyelet from thespindle of the'lower setting die 6 afterthe setting operationr The driving shaft 30 has secured thereon at hand wheel 32 and a pulley 34 by which the machine may vbe driven from any suitable sonrcelof power. a The pulley 34.nor mally runs loosely upon the shaft but is adapted to belclutched thereto whenever the clutch zring 38 shownin; Fig. is released. This ring comprises, part of the well known Horton clutclr The clutch ring 38 is held in position for causing the clutch to remain disengaged by a stop arm l0 secured to the rock shaftwi fi; When it is desired to start the machine thearm a0 is lowered outofthe path oftheproj ection on the clutch ring38. lt is desirable to prevent non-repeating action of the clutch and to .this'end mechanism is provided for returning the armLO to stopping position after it hasonce been dee pressed far enough to permit the machine to start. Loosely mounted on the rockshaft 36 is a-tripping arm iicarrying a dog L6, The dog (i6 is arranged tohook over a projectionv50yon an arm 52 which is fast to the rockshaft 36. A cam 4:7 on the drivingshai't is arranged to swing the dog ,46vout of engagement with the projection as soon as the machine has been started and holdit inadisengaged position until one cycle; of the machine has beencompleted. When the dog 46 hasbeen disengagedfrom the projectionjOon thelever52 the latter is immediately moved upwardly by a, compression spring which bears on its rear end andthevrock shaft 36 ,rotated to bring the stop arm 40 into the, positionl shown in F g- If L a In order, toinsure a prompt stopping of the machine an eccentricrdisk 56is mounted upon the driving shaft 30 and a'brake shoe 5% is connected by a link 60 to a short arm onithe rock shaft 86 so that the brake will be withdrawn or applied simultaneously with disengaging or engaginguthe-clutch. A handle 58 is operatively connected with the brake shoe 5a so that the latter may be loosened in case it is desired to turn the driving shaft by hand. :A spring presser I pin 62 tends normally to move the clutch shoe into operative position.

When the machine is operated by power the; treadle rod 42 by which thevclutch is controlled has a lost motion connection with the treadle 86, the arrangement being such that the initial depressionof the treadle 86 will swing the punching die for perforating the work and its further movement will depress the clutch rod 4L2 and permit the clutch to become engaged. i H p H \When the machine is operated under powerthe raceway'is movedby the mechanism above described but when the machine is operatedby foot power, the cam lever 77 6 is "replaced by an arm 100. which-may be secured to the outer end of the rock shaft 2a and provided with a boss to make connection with the cam bar is similar to that made by thecam lever 76. The arm 100 is indicated in dotted lines in Fig. 1.

In operating, the machine the material in which the eyelet is to be set is introduced between the stripper 8-1 and the punching die82. Thetreadle is then depressed and the work forced downwardly upon the perforating spindle of the lower setting die. As the point, of the spindle passes through the work'itentersrbetween the sections of the punch die 82 and slightly separates them as indicated in Fig 'l. Meanwhile the lost motion; between the treadle and the clutch rod 42 has been taken up so that further de in pres sion of the treadle swings downwardly the tripping arm Hand, through the :mech: anism above explained, causes the clutch to become, engaged tand the machine started.

Thereupon thetupperset'ting die is lowered first to engagewithits spindle the endmost eyelet in the racewayand then, as the raceway is withdrawinto separate the punching die se'ctions,; insert the eyelet and finally 4 clench it against the lower setting die iThe power actuatedparts are subsequently re turned to their initial position and the machinestopped; Then, when thetreadle is released, the punching dieplate and stripper 84: are raised and the latter removes the work and the clenched eyelet from the lower setting die, thus leaving the machine in con dition for setting a new eyelet.
